  Hello ,,, sorry you are having trouble ,    The flywheel guy is Elbert Faris , ( he's the spitting image of the late comedian Foster Brooks )  but he has only done wico flywheels , He puts in a new center hole with steel disc riveted  to original part ,  he puts three holes in the steel disc for the puller / pinion ,       a little spray paint on the magnets and the laminated pole parts should revear the culprit in short order maybe pull a plug and turn over slowly and look for "wobble " of flywheel ,  ( if it is a small amount it shoild still be ok A dial indicator would show if crank is bent  ,  maybe even woodruff key too large ?  stuff like this can really tax your patience,   I hope problem is small with a quick fix !      Take care ,,, ;D  Larry.

The last time I talked with Wayne, he was trying to find a replacement flywheel. On thing to keep these bikes running the other was to get it to have a 12volt supply. You may ask to see if he any closer to getting a break Thursday on this.

If you don't have any other sources or offers, you can send your flywheel to me & I can see if I can fix it.  I've still got my flywheel off & can use my motor for a fixture.
Just let me know.

Sitting in the garage thinking again. Trying to figure out why I am having so much trouble with that flywheel rubbing . Does this picture look correct I have a 1/4 inch here.

Jeremy,  it is hard to see what you are showing there.  Did you get a new flywheel from Wayne?

Jeremy , I bet you a brazillian dollars this could be solved over the phone ,  I figured out that you have a tape measure between the crankshaft counterweight and the crankcase , ???   tightening the pulley , ( left hand thread should draw the bearings tight together and the crank should spin free ( unless it is bent , )   does installing the stator plate bind things up ? if so suspect bent crank , ( i have straightened them )  remove parts until crank spins free and give it a few turns as you put the engine back toghether  please feel free to give a call   314 609 6568     Larry.

After phone conversation with Larry I assembled engine. I was very pleased with how easily the bearings came out after the oven trick. I am pretty sure all the bottom end is ok back together every rolls easy until I install flywheel I painted laminates and it hits everyone I heated and removed center hub from flywheel once again put it on the crank tightened completely and spun crank holding rod post hub hobbled pretty bad can't pinpoint why. I then pulled hub back off and made a pointer with a roll of solder pointed right below treads on crank, as suggested by Larry crank ran true. Something is wrong with that hub it seems. On the bright side I now feel better about the bearings and crank

It would seem the hub somehow is " wacked "       might maybe think on removing hub from flywheel that came from outboard ?      maybe for giggles and grins try fitting other flywheel (even tho it's not for that machine ) to see if any binding ,,,,  looks like progress is happening ,  and culprit is being narrowed down ,,,,,      ;D     all the best ,,    Larry.

I wonder how close a lawnmower crankshaft is to a simplex one, regarding the tapered nose where the flywheel mounts.  If they are the same, a guy could take a junk lawmower shaft & cut the nose off so you could mount it in a lathe.  This would provide a mandrel that you could mount the hub to so you could both measure and re-machine the notch which fits into the stamping to square it up.  You also need to check to see what the runout is on the stamping itself.

 Just reviewed photos and the outboard flywheel tapered hub too big for trial fit ,    ,,, can't imagine how hub can be " off"     ,,,, can't be too hard to reproduce ,,  maybe it just needs the mating surfaces cleaned up better before brazing back together ?         Food for thought ,     We'll all sleep on it     Larry.

Wish I could do something with that outboard flywheel but the hub is drilled for a smaller diameter crank also the whole thing is smaller . I do have a 5hp. Brings horizontal laying in the junk may look at it for ideas

Haven't posted my progress on the Simplex lately because that flywheel caused me a catastrophic mental breakdown. Plus got busy at work, however I got a box and bubblewrap today , going to send it off tomorrow, with a little luck next time I see it problem will be gone. I truly thought that would be an easy fix I will be curious to know what Wayne finds.
